Application filed November 1. 1913. Serial N0. 798,731.

T0 all wlwm z't mrzy concem Be it known that I, CHARLES J. BRINK- MANN, a, citizen 01 the United Staates, residing at Glencoe, in the county of M0Leod und State 01 Minnesota have inventad ce1tain new and useful Improvements in Automobile-Horns, 0f Which the following is a specification, reference being had 150 th@ accom panying drawings.

This invention comprehends certnin ncw and useful improvements in autornobile horns und has for its primary object t0 provide a device 0f this character including a plurality of tubes secu1ed 2111 their oute1 enc1s t0 a central support and having thci1 inner ends With the inner end of the centml support sec1ired to a head adapted to be connected with the exhaust port 0if the mxto mobile engine, said inner ends 0f the tubes being formed in such manner as t0 give an audible signal when the exhaust gases pnss throgh the same 1:0 the surrounding atmosphere.

Another object is to provide a device 0'F this character including ai1 vents havinp;

bylindrical inner ends tapped intxo the head Whi1e the inner ends 015 the resonant tubes are sp1it and engaged around the flattened outer ends of the air vents, said tubes having aixescape opening;s at the outer ends 01' the air vents with wings t0 opposife sides and straight flattened outer edgos against which the exhaus't gases from the mufller will impinge as they pass 0ut of the discharge 01' outer ends 01: the air vent, und sound a note of a di:fFerent pitch in each tube, as Will be readily understood.

A further object is 130 generally improvo and simp1ify the construction of devices 01: this character and increase the efficiency 013 the SLII1G and ab the same time decrease the cost of manufacture 0f the device.

With the above and other objects in view, my invention consists in certain novel c0n structio'ns, combinations, und arrangements of parts t0 be hereinafter more fully described, claimed, and illustmced in the accompanying dmwings, in which,

Figure 1 is a perspective view of the complete device; Fig. 2 is a transverse sectional view through the head 4, looking toward the outer end of the device, the resonant tubes being removed; Fig. 3 is a transverse seetional view through the centml support 011i:- wardly of the air vents, looking inwardly toward the head, the resonant tubes being removed. Fig. 4 is an enlmg@d detai1 perspective view 017 the inner end 0f one 0f the pipes, und the ai1 vent carried thereby; und F:ip;. 5 ;is an cnlurged detni1 fragmentary sectionnl view, showing the mmmer in which the outer ends 0f the tubes a1e secured upon the central support.

Referring more specifically to the drawings in which similar reference characters designate corrcsponding parts througlmut the several views, 1 designates the central support aronnd which a1e positioned the resonant tubes 9, which unbes am spaced in parallel relation t0 the centml support 1 and surround the same, said tubes being securvd ab thei1 unter ends t0 said centra] support l, by co-acting laterally projecting slip-joint members 3 and 3.

The inner 011d of the central support 1 and the inner ends 0f the tubes 2 a1e tapped into the head 4:. The inner end of the cantra1 support 1 is tapped into the head 4 while the inner ends of the rcsonant tnbes 2 .mre cngaged against the head 4: and rednved, said reduced inner ends of tl1e tubes 2 lwing split longiti1dinally and engaged around the oucer flnttened ends of the air vents 5, :1s shown a1; 6. The inner ends 0f the air vents 5 :u-e of cylindrical forn1 und tapped into the head 41 around the inner end of the central support 1 and outwardlv 01 the Same, as will be readily understoo by referring to the drzuvings.

'lhe tubes 2, ns will 100 understood, are of (lifl'c1e11t lengths und have the :1i1 escape openings 7 formed in their outur faccs a'L the outer 01 dischmge onds of the air vents 5, the si 1e wn]ls 01 euch :1ir escape opening being extended outvmrdly und parallel to 0110 21110131101 t0 fm:m wings 8, while the Wall 0f tbe ail escupo opening opposito the dis chmge end 0f the ai1 ve11t is fluttened whoreby a stmight sge 0 is provided aguinst whiuh th 3 exhuust gases 11'0111 the mufller will in1pinge us they pnss 01112 01 the dischznrge end 0E th0 air vcnt und said mit vents am so zurungml that said exhuust gnses Will sfriko exact1y at the st1aight edge 9 und emmd a. note 0f a d1fl'erent pitch in euch tubo9.

will 110i; readi]y become disengaged from ehe laterally. projecting member. The slip joints may be readily fastened 011 the outer ends 0f the pipes and disengaged completely from the cenrml support l, when the pipes are being secured to the air vents 5 01 re rnoved from the sa1ne. It Will be se en that while the immer Qnd 0f 0ne pipe is being secured t0 the airvent for the same 01' disengaged from said air vent, the remaining pipes Will.

be reaclily he1d in osition by the Slip joint members 8 and 3.

From the foregoing, it Will be clearly ap parent that I have previded an automobile horn 0f extremely simple und cheap c0n 1 struction and which Will be highly efficieni and effective in use. It Will also be readily seen that owing to the manner in Whi0h each resonant tube is independently secured 130 and spaced from the centml support and has its reduced inner end secured around the outer flattened end 0f the ai1 vent provided 'f01 the same andtapped. into the head,. euch tube nmy be readily securecl in p0sition or renwved without disturbing the other eube or tubes.. Itwil1 further be seen (hat while I have shown the preferred em bodiment of the device, I d0 not wish to be limited to the same, as minor changes in the details of construction may be made within the scope of the appended clai1ns without departing from the spirit 0f my invention 01 sacrificing any of the advanages'0f the szi'me. Itw1ll also be seen that whfle I havesh0wn the dev1ce as mcl-ud1n;; fiv resonant y tubes, any suitable number may be employed.

VVhat I claim is 1.A device 0 the dass described comprising 21' head, a plurality of air "ents detachably mounted -in=szuid head and projecting therefrom, a central support projecting from the head, a plurality 0f resonant tubes, each cf szudtubes havmg an zur escapeop en1ng formed there1n achacent 1ts 1nns1 end, each tube being split longitudinally from theinner Wall 0f the openin g therein 130 the. inner edge 0f the tub e -t0 provide a pair of wings the split portion of each tube being adapted for sdab]e engagement with the projecting end 0f 0ne 0f said air vents, and m'eans f0' loosely connecting the outer end of each tube to the central su=pport.

2. A device of the dass deseribed comprising a heada central support projecting fromm the head a plurality of reson-ant tu-bes a plurality of air vents cznrried by the head and having reduced ext-ended portionsthe inner encl of euch tube being engaged around the extended portion 0-1 one 015 said air. vents,. a plum1ity 0f laterally projecting s1ip j' 0ill members carried by the central" support, and

a lntemlly projecting Slip joint socket member carried by the outer end 0f eachtubw und adapted f0r engagement with on e of said laterally projecting Slip joint .members ca1ried by the central support.

In. esimony Whereof I he reunto ziflix may signature in the presenceof two witnesses..
